- 适合用于采矿机器人规划、训练与数字孪生系统。
地下采矿机器人在路径规划、操作员培训和数字孪生流程中日益依赖可靠的执行器级运动学模型,以减少现场高危试验。不同于典型的开链工业机械臂,典型采矿设备常为由直线执行器驱动的闭链机构,带有平面四连杆结构,导致可复用的运动学建模与实时正/反解求解困难。本文提出 extit{MineRobot},一个面向该类机构的执行器中心化建模与求解框架。它引入采矿机器人描述格式(MRDF),一种具有执行器与环闭合语义的领域专用表示。通过将平面四连杆子结构压缩为广义关节,并为每个执行器提取独立拓扑等价路径(ITEP),按四种标准类型分类。基于此分解,构建分类型正解流水线,反解则表述为带边界约束的执行器长度优化问题,采用高斯-赛德尔风格更新求解。通过将耦合闭链运动学转化为小规模拓扑感知求解,减少机器人特异性推导,支持高效重复的正/反解计算,无需将每次查询视为完整耦合约束求解。对代表性地下采矿机器人的实验表明,该方法实现实时正解性能与测试范围内的稳健反解收敛,支持其作为规划、训练与数字孪生流程中的执行器级运动学层。
原文摘要 · Abstract (English)
Underground mining robots are increasingly modeled for planning, operator training, and digital-twin workflows, where reliable actuator-level kinematics is needed to reduce hazardous in situ trials. Unlike typical open-chain industrial manipulators, representative mining machines are often linear-actuator-driven closed-chain mechanisms with planar four-bar linkages, making reusable kinematic modeling and real-time FK/IK solving challenging. We present \textit{\hl{MineRobot}}, an actuator-centered framework for modeling and solving the kinematics of this representative mechanism class. MineRobot introduces the Mining Robot Description Format (MRDF), a domain-specific representation that parameterizes mining-robot kinematics with native semantics for actuators and loop closures. It then contracts planar four-bar substructures into generalized joints and extracts, for each actuator, an Independent Topologically Equivalent Path (ITEP) classified into four canonical types. Based on this decomposition, per-type solvers are composed into a sequential forward-kinematics (FK) pipeline, while inverse kinematics (IK) is formulated as a bound-constrained actuator-length optimization solved by a Gauss--Seidel-style update scheme. By converting coupled closed-chain kinematics into small topology-aware solves, MineRobot reduces robot-specific hand derivations and supports efficient repeated FK/IK computation without treating each query as a full coupled constraint-solving problem. Experiments on representative underground mining robots demonstrate real-time FK performance and robust IK convergence within the tested operating ranges, supporting the use of MineRobot as an actuator-centered kinematic layer for planning, training, and digital-twin workflows.
